Lyrics:

Yakko:
There are fifty-thousand different kinds of animals
And there are fifty-thousand more that used to be
There's a hundred-million ants
And half a billion plants
And a lot of fish down underneath the sea

There's gotta be a couple million spiders
A hundred-fifty million butterflies and bees
And a bunch of different mammals
Like those elephants and camels
And approximately fifty-billion trees

Y+W:
But there is only one of you
That makes you special
You stand out among the other things; it's true

YW+D:
Yes, the universe is large
And whoever is in charge
Made lots of things, but only one of you

Yakko:
A one, a two, a three, and a four
A thousand and a million and a billion or more

There's a trillion drops of water in the ocean
And a billion trillion molecules of air
There are insects here en masse
And a trillion blades of grass
And a thousand strands in every head of hair

A lot of little grains of dirt make up this planet
A billion atoms on the head of every pin
A million birds that all can fly
A trillion stars up in the sky
And all the many different people there have been

Y+W:
But there is only one of you
That makes you special
Yes, there is nothing else exactly like you are

YW+D:
Cause you're unique and you're terrific
And you're kind of real specific
Cause there's no one else the same
As the person you became

Wakko:
In fact, you're kind of weird

Yakko:
But we like you just the same

YW+D:
Cause you're the only one of you there are
Ba ba boop-um
Ba ba doop-um
Ba ba doop-ba!
